I have a question concerning Ignite mechanics. There has been a lot of discussion about (no more?) ignite munching, so I checked WWS and got some results I cannot explain.
To get the expected amount of Ignite damage, I calculated (number of critical hits) * (average critical damage) for FFB, Pyro, LB and Scorch, and multiplied the sum by 0.4.

WWS - Patchwerk - my calculation shows I should be getting about 178k of Ignite damage. However, I did get more than 200k of Ignite.
WWS - Loatheb - expected Ignite amount 328k, but got only 305k.

I specifically did not use any means to avoid Ignite munching, but tried to execute the best dps rotation. The only difference I can think of (aside from the ~90% crit for Loatheb) is that I am standing very close to the boss there, whereas on Patchwerk I did stand ~30 yards away.

Do you guys get similar results? Or were my calculations just wrong... these results would suggest that it is actually benificial to ignore the ignite-munching problem and just cast pyro whenever Hot Streak proccs, no matter if a FFB is in mid-air.

I suggest you read/search all threads on this forum first, this will give you an answer to almost every possible question. To know what are appropriate questions you can check out the first post of this thread.

Did anyone model the effect spell penetration has on partial resist ? I mean is that a way to derive the ballpark basic school resistance a boss has from his average % partial resist.

For the sake of argument let say that on boss X, a FFB is always mitigated around 2.7% ( partial resist ) , is there a way to know what resistance he is likely to have ? ( let say 120 for example ).

I understand spell penetration is unlikely to ever be a stat worth stacking, this said some pieces do come with spell penetration on it, it would be interesting to know which bosses they may be the most useful on and to put a value on it. And such a table would be nifty

All the research that has been done (none recently) has shown that spell penetration has little to no effect on partial resists on bosses.

This is due to the boss partial resists being a rsult of level difference and not actual resistance value.

On trash in 5-mans or raids, the mobs will usually die in around 20 seconds when single-targeted. This is less than the time for two Living Bombs. In raid situations, there will often be a point where a Living Bomb explodes and there will be less than twelve seconds before the mob will die. Assuming a deep fire build (either post-patch Arcane/Fire or current FFB).


On trash that will die in less than 20 seconds, is it better to delay the initial Living Bomb cast so that the explosion will happen in the final 35%?

If the mob's time to die is under X seconds, what's the optimal cast? I assume at under 1.5 seconds it's Fire Blast and at under 3.0 seconds it's Fireball/FFB, and for 12.0 seconds or more it's Living Bomb, but what about for less than 6.0, 9.0, and 12.0 seconds?

I've been planning for 3.0.8 and the 18.53.0 build. The gear set I'm looking at is similar to above, but as I lack JC, it looks like the following:
[Valorous Frostfire Circlet]: [Chaotic Skyflare Diamond], [Runed Scarlet Ruby]
[Wyrmrest Necklace of Power]: [Reckless Monarch Topaz]
[Valorous Frostfire Shoulderpads]: [Reckless Monarch Topaz]
[Pennant Cloak]: [Reckless Monarch Topaz]
[Heigan's Putrid Vestments]: [Glowing Twilight Opal], [Reckless Monarch Topaz]
[Bindings of the Expansive Mind]
[Valorous Frostfire Gloves]: [Runed Scarlet Ruby]
[Leash of Heedless Magic]: [Glowing Twilight Opal] (Eternal Belt Buckle)
[Valorous Frostfire Leggings]: [Runed Scarlet Ruby], [Veiled Monarch Topaz]
[Boots of Impetuous Ideals]
[Signet of Manifested Pain], [Signet of the Kirin Tor]
[Dying Curse], [Embrace of the Spider]
[The Turning Tide], [Surplus Limb]
[Gemmed Wand of the Nerubians]

I've gone through all the options, making sure all the correct buffs and whatnot are there. I'm using the scribe enchant on shoulders. I'm also Draenei, so I always have the extra hit.

All that being said, I've been playing around with gear, and in all cases I've found that Embrace of the Spider is showing higher DPS than Dragon Soul (when Dragon Soul is adjusted down to 200 spell power from 260, as it currently exists on the PTR). The difference varies about 20-30 depending on which gear I plug in.

Has anyone else had these results? Have I plugged in wrong gear such that Embrace gives higher DPS, but Dragon Soul still would be better if with a more optimal gear set? Try as I might, I just can't find the latter situation, but that's not to say it does not exist.

*Edit, Fixed the Trinket/OH error.

I admit I never thought of making a gearset with 3 trinkets.

I'm using Rawr 2.1.6, and that absolutely was the issue. It's now valued as I'd expect/seen in the past. Thanks for the help.

Might want to swap that gem in your neck with the one in your belt.

Actually, sp > haste still right?

So put that blue gem in your belt and a +19 SP in your belt buckle so you get your socket bonus for the neck.

Yes, spell power is a larger DPS increase (point-for-point) than haste rating, for both fireball and frostfire specs.

After Rawr 2.1.6 was released, I took the liberty of measuring scale factors in Rawr for both 18/53/0 (fireball) and 0/53/18 (frostfire), based on Enthorn's "perfect gear" setups at the top of page 16 (which I was also able to verify as the top gear sets for each spec). These were obtained by simply adding 100 of each stat and measuring its individual impact on DPS.

18/53/0 fireball (6218 DPS)
Spell power: 1.5811 DPS per point
Haste rating: 1.4469
Crit rating: 1.3106
Intellect: 0.3955

0/53/18 frostfire (5823 DPS)
Spell power: 1.5316 DPS per point
Crit rating: 1.4246
Haste rating: 1.3013
Intellect: 0.4304

Spell power is the strongest non-hit stat for both specs. For fireball, haste takes precedence over crit (and vice versa for frostfire--the two receive nearly identical benefits from opposite stats). In general, fireball makes better use of spell power and haste rating, and frostfire better utilizes crit rating and intellect.

Yes on the Upcoming change thread there is a long discussion on the use of the AB buff. To boil it down yes the ABar spell damage is calculated on cast while the AB spell damage buff is active until the last AM hits the target. Whether or not this is intended or will be changed by Blizzard is unknown, but it is the same mechanic that Frost mages use to get the phantom 3rd charge on FoF procs (FrB-FrB-Lance) while the lance is useful.
